Cutting range from Schlicht

Compounds benefits for cable manufacturers Electric Cable Compounds (ECC) provides two flame-retardant elastomeric cable filler compounds that are pelletised, extrudable, non-halogenated and RoHS compliant. CableFill ® 200 and CableFill ® 300 are designed to provide the following benefits to cable manufacturers: • Maintain cable shape • Prevent deformation/stress of cable components • Fill gaps/voids • Provide additional flame- retardant benefits to overall construction • Reduce water ingress • Isolate individual cable component contact • Do not detract from/may enhance overall cable flexibility • Colourable • Easy peel • Easily processable at low temperatures

The product range of Rolf Schlicht includes system solutions for versatile cutting tasks. The company offers a wide range of semi- or fully automatic winders with strapping, setting, shrinking and ejection/storage systems on pallets or conveyor belts. The field of application for its systems is the production area of plastic and rubber extrusion for manufacturing hoses, tubes, profiles, strips from small diameters to less than 1mm in medical technology up to tubes of approx 100mm diameter. The company supplies feeding and cutting systems in GMP version for the pharmaceutical industry and medical technology for the clean room. The systems work in the extrusion line or outside the line from the coil, from the winding band or out of the pallet. The systems are adapted to the needs of the customers in order to achieve the best possible effectiveness. The different feed, discharge and picking devices are made to customer specifications. The RS Multicut type MC NG is a cutting unit for the precise cutting of soft and semi-hard extrudates to diameters of 25 to 100mm. The line speed can be up to 200m/min. The position of the rotating blade is continuously monitored by the controller and can accelerate to maximum cutting speed, which ensures a minimum blocking time of the product. Cutting frequencies up to 3,000 cuts/min are feasible. RS Multicut Caterpillar type RB is characterised by its robust construction and up-to-date technology: state-of-the-art control, quick release of the puller belts without tools, latest drive technology with servo-direct drives, wide range of products with caterpillar belts of 50-200mm width, belts or contact lengths of 250/600/1,000mm, as well as special designs, and special equipment according to customer requirements, such as wet cutting, particular material guides, measuring and detection systems, slotted devices, etc. Commissioning devices for quick and automatic removal of cut parts in drip pans, containers, cartons or bags is also possible. RS Multicut Orbital cutter type OC is a cutting system for precise, fast and clean cutting of semi-hard and hard pipes made of plastic, rubber, plastic composite with aluminium or copper pipe inside or rubber with Kevlar, etc. RS Multicut Scissor cutting system type SC is a scissor cutting system by means of cam and servo technology. Cutting at standstill to achieve best length tolerance, angular cutting, unique cutting sequence, more than 300 cuts per minute are possible. This is used for profiles in the construction and furniture industry, scanner strips, semi-hard and hard materials. RS Multicut Combi-Cutting machines type CC consist of the approved caterpillar and the rotary cutter from the machine series RS Multicut for cutting plastic and rubber profiles and hoses. In the caterpillar take-off, a servomotor with digital drive controllers guarantees a precise and constant transport speed of the product. The speed signal is processed internally to control the integrated rotary cutter. The downstream rotary cutter works by means of an electronic cam application. Based on the production speed, the selected cutting speed and the nominal length, an optimised motion profile of the cutting blade is continuously calculated so that the product is cut vertically and cleanly between the two matched product guide bushings with maximum cutting performance. This cam application combines the advantages of clocking with continuous operation. The application ensures optimised length precision. All process-related parameters can be changed during operation on the control panel. Rolf Schlicht GmbH – Germany Website : www.schlicht-gmbh.de

Typical applications include low toxicity transit, mining and shipboard cable. CableFill300, which is the more highly flame retardant of the two grades, has an LOI of 48. CableFill200 has an LOI of 36. Both compounds are engineered to be processed on conventional extrusion equipment. ECC is a supplier of high- performance, elastomeric and polyolefin-based cross-linkable and thermoplastic speciality compounds.
